"I remember games where you could dig up treasures and things like that, but that was clearly different from movement/action. You could still do it by brute force, but it was basically impossible due to the size of the map and the time it took to try to dig." --> That's exactly what I'm looking for.
The problem is when the move button is the same as the one you would use to dig, which is what happens to me with the native mouse behavior. I could also disable events until clues are found, but it seems more organic to me if the player decides to activate “action” on one of the 100,000 squares on the forest floor and JUST happens to be on top of the “treasure” and finds it. Such luck would deserve a prize. Imagine the look on their face. I'm sure they would start digging all over the map :D
I'm working on a plugin that keeps the left mouse button to move, but doesn't activate the action button, which will be triggered by the right mouse button or the keyboard.
(Sorry for my english...)
